I'm tired of my PTT's squeaky brakes (I believe this is a known feature of all Panameras). I know I can reduce the squeaking through one or two agressive breaking sessions, but the squeaking always seams to comes back after driving in city traffic.
Has anyone tried the Posi Quiet Front Brake Pads?

 

I have a 2016 GTS with approx 10K miles. Bought new. There has never been a brake squeaking issue.

 

15 Pana 4, standard brakes, no noise at 17K so far. I d guess that the pads on your PTT can be changed out to a pad that will be quiet. or maybe just a standard Pana pad and not the turbo model pad whatever the difference. Your choice would probably work too.
